ZBNF is a set of farming methods, and also a grassroots peasant movement, which has spread to various states in India.
According to the “zero budgets” concept, farmers won’t have to spend any money on fertilizers and other agricultural inputs.

• Over 98% of the nutrients that crops require — carbon dioxide, nitrogen, water, solar energy — are already present in nature.
• The remaining 1.5-2% are taken from the soil, after microorganisms convert them from “non-available” to “available” forms, for intake by the roots.
• This is where the special package of practices which, Palekar says he perfected during the 1990s at his 36-acre farm in Belura village of Amravati district in Maharashtra’s drought-prone Vidarbha region, comes in.

Four Wheels of ZBNF

• The “four wheels” of ZBNF are ‘Jiwamrita’, ‘Bijamrita’, ‘Mulching’ and ‘Waaphasa’.
• Jiwamrita is a fermented mixture of cow dung and urine (of desi breeds), jaggery, pulses flour, water and soil from the farm bund.
• This isn’t a fertilizer, but just a source of some 500 crore micro-organisms that can convert all the necessary “non-available” nutrients into “available” form.
• Bijamrita is a mix of desi cow dung and urine, water, bund soil and lime that is used as a seed treatment solution prior to sowing.
• Mulching, or covering the plants with a layer of dried straw or fallen leaves, is meant to conserve soil moisture and keep the temperature around the roots at 25-32 degrees Celsius, which allows the microorganisms to do their job.
• Waaphasa, or providing water to maintain the required moisture-air balance, also achieves the same objective.

Astra’s of ZBNF against pest attacks

• Palekar also advocates the use of special Agniastra, Bramhastra and Neemastra concoctions — again based on desi cow urine and dung, plus pulp from leaves of neem, white datura, papaya, guava and pomegranates — for controlling pest and disease attacks.
• ZBNF uses farmyard manure or vermicompost mostly produced from Eisenia fedita, a species imported from Europe and Canada.
• These foreign earthworms accumulate heavy metals like lead, arsenic and cadmium, which get transferred into their castings that, far from being manure, are actually toxic to the soil.
• So, the soil fertility, instead of improving, only reduces.
• He says that in ZBNF, the work of making nutrients available to plants is done exclusively by microorganisms from Jiwamrita and local earthworms.
